materials for insulatet heating element
(OP)
Hello gentlemen, I'm trying to produce a heater element to be incorporated into a steel valve body to maintain fluid temperature in the 1000K ballpark. Obviously I can't simply pass a copper wire so I'd be very grateful if anyone could give me the commercial names for the materials commonly used in heater elements as found on electrical stoves, etc, that have the steel pipe which glows red, ideally with some sort of internal filling to fill the air space inside for optimal thermal conductivity between the copper coil and the casing.
Thank you very much.
Thank you very much.

RE: materials for insulatet heating element
Typically some thing like nichrome does the actual heating, and a variety of ceramic materials are used for insulation

Thanks for the replies so far I'll check them out.

the outer sheath is usually alloy 800, the heating element is nichrome or a similar high temp high resistance alloy, and they insulation is magnesium oxide. They string the wires inside the tube and fill with powdered oxide. Then they draw the tube down to a smaller diameter to consolidate the insulation.
Buy them, these are highly engineered products that rely on specific relationships of heat transfer and electrical resistance to function correctly.
